Question System Won't turn on

I knew I had to update the BIOS on this board (GIGABYTE B650M Elite AX) before using it with my 9800x3d so I followed the steps to use Q-flash before any hardware was connected to my board. Everything seemed to work and complete fine. Now with CPU, RAM, fans, cooler installed the system does not turn on.

When I flick the switch on the PSU the purple lights on the bottom right corner of the motherboard show or a split second but turn off. During this I never see any of the diagnostic lights come on. My keyboard and mouse are still getting power even after the purple motherboard lights went away after a split second. However nothing else happens, fans don't move and the monitor does not detect anything. After this I tried using the RST button on the motherboard and I tried clearing the CMOS with the jumper. Still the same result. So I tried to do Q flash again, this time with everything connected, this time with F30 instead of F33a.

Once I pressed and held the Q-flash button for a couple seconds the system showed some life with the fans and pump starting to run, again system seemed to complete the Q-flash BIOS update fully. After confirming it was done and waiting about 30 seconds I turned off the system, removed the USB, turn on and same issue as before. One thing I did notice as I was running Q-flash the second time was that the CPU light was on even though my CPU was in the socket. I know I definitely had put the CPU in the right orientation and it was seated properly.

I am not sure where to go from here. During this I have never connected a GPU or SSD.

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Looking up the motherboard, at the time of writing, the board has a couple of revisions. I could 3. Did you verify that you sourced the right BIOS version off the right version of your board's support site?

Rams populating slots A2 and B2? You might want to inspect the CPU's socket for any bent or broken pins. On the topic of pins, if you're working with a cooler that needs to fastened down, relieve some pressure from the cooler's mounting until it's merely resting on the CPU's socket. Bent pins can prevent your platform from powering up.

Speaking of platforms, did you breadboard the system before assembling them in the case?

Updated the post to show all my specs.

I am using the BIOS for ver 1.3 that I own. pulled directly from gigabytes website. I am using slots A2 and B2. I did check to see if any pins were bent before installing and didn't see any, but at this point I might need to do that. I did relieve some pressure from the CPU but I will go-ahead and try to relieve some more. My system is currently outside of the case laying out on a bench.
